Of those apps I can only say that VS Code is well written and that Spotify is junk.

Is 600mb too much for VS Code? I guess it depends on what you are doing with it and which extensions you have installed etc., if you are running a pretty bare-bones installation and seeing 1GB+ memory usages in VS Code please open an issue in their issue tracker and tag me (same username as in HN).

And that didn't happen by switching to the website approach, I think you'll be disappointed if any of these apps end up switching to Tauri or Wails without significantly improving their code too. Which is why I'd predict no major player will jump ship.
